OPERATING MECHNISM FOR WINDOWS Filed March 31. 1932 Inventur Frank X -B Bp Attmrney Patented Mar. 21, 1933 FBANKX. MPP, oF MADIsoN, Wisconsin OPERATING MECHANIsMroawINDoWs Application ledMarch-Sl, 1932. Serial No, 602,337.y

The mechanism has been so designed that it may beinstalled at the mill on the component parts of a knockdown Window.

The. improved operating mechanism is characterized by a simple and inexpensive bearing 1nember, by a novel k mounting of a laterally swinging screw shaft and by ga provision forjclosing oil' a recess in the support to prevent the incursion oi foreign. matter and insects. V

A practicalembodinient of theinvention is illustrated in the accompanying drawing, in which: Y y

f There is shown a portion o f'a window frame. consisting of vthe usual stilesj, sill vand stool(7 A sash (8) is'-`1nounted `4Q in the frame for combined sliding Vand swinging movement by means 'et arms .9 positioned inalignment at thetop landgbottoni of 1thefgsash and each carryinga rollerl() ,riding in. a Achanneled trackwaylldn the 4,5 frame.

A f T116 Operaties insli-Disn ifOI @Paling uid closing .the sash' comprises` a lever 12 and a screw .shaft 13.., The lever is fulcrumed in a plate'llsecured to-thesill and pivotally re'- 5 0 tained in a s imilarplate securedI tothe ated withoutdisturbing the sash or screen.

. vA sleeve undersideof the sash.- The plate 15 and the lever are ittedinto .a recess 16 when the sash is closed. The lever is provided With an aperture 17 for receiving a removable pin lrfpivotallyA attaching the fork 19 `on the 55 outer end ofthescrew shaft 13.

. 'lhe mounting of the screw shaftis placed more or less centrally of the sill and is dis@ posedin.V arecess 2() inaA fnrring strip 21 that "isinserted, between the sill andthe 6o stool `The mounting consistsy oa bed plate 22 secured by screws 23 and havinga 'nger 24 on ,its rear end provided with an aperture 25"'for receiving thefpivot pin 26 oan lelongated bearing member or barrel. The bearing member consistsfof a flat bot-y tom plate .27 4and an'arched 'top plate 28 f havinglugs 29 inserted through aperturesin the bottom plate and then upsetto Lprovide afrigid assembly. The rearend 3 0 of the 704 bottom plate is offset and the front endf in angled so that the surfaces inengagement y with the bed plate will be reduced to-a mini-4 32y within 4the bearing member -75 hasacollar 33 onitsforward'end'provided Y internally with screw threads 34 to forma nut.`V The sleeveis inserted inthe bearing member from the frontu'ntilffthe collar`33 abutsfthe forward face of the bearing memf ber.

the screw shaft 13 during the swinging' movement. v

An arcuate shutter 42 for closing the aperture 41 is confined between the guard plate and the front collar 33 of the sleeve and preferably rides on spaced lugs 43 at each end of the slot 44 in the bedvplat-e. The shutter is of less length than the guard plate and has an aperture 44 positioned at one side of its center to receive the screw shaft v13 and to be moved laterally thereby.

By virtue `of the reduced length ofthe shutter it will not project beyond the guard plate when carried along with the screw shaft and yet it will close the aperture`41 throughout the stroke of the screw shaft lwhen the sash is being opened and the screw shaft is being` laterally displaced in this operation. s

In order that the shutter may be applied to a window opening on either a right or a left handed pivot it is only necessary to rotate it 180 degrees about the screw shaft (Figs. 4 and 5). 'To permit of this revers'- ing=adjust`ment a slot 44 is provided in` t-he bed plate 23 rto allow passage of the small end of the shutter. The adjustment may be quickly made without removing the screw shaft 13.
